Duct Inspection & Cleaning

Clean Ducts, Healthy Air, Efficient Systems

Your HVAC system is only as effective as the ductwork it depends on. Over time, ducts can accumulate dust, mold, debris, pests, and structural damage — all of which impact airflow, air quality, and energy usage. At SMI HVAC Services, we provide detailed duct inspections and professional cleaning services for commercial and residential properties throughout Santa Maria, Santa Barbara County, and nearby regions.



Whether you manage an apartment complex, operate a commercial kitchen, or simply want cleaner air in your home, our team delivers service with integrity — never using scare tactics or inflated claims.

Our Process – Inspection, Cleaning & Solutions

Step 1: Ductwork Inspection

We begin by inspecting your duct system from end to end. This includes:


  • Visual and video inspection of duct interiors
  • Identifying crushed, disconnected, or leaking ducts
  • Checking insulation and airflow at key junctions
  • Spotting signs of moisture, mold, or contamination


For commercial properties, we also check for compliance with local airflow standards, especially in kitchens, labs, and high-occupancy spaces.

Step 2: Duct Cleaning

Once we assess the condition of your ducts, we perform targeted cleaning using professional-grade tools. This includes:



  • Source removal of dust, pollen, pet dander, and debris
  • Agitation tools and negative air machines to loosen and vacuum buildup
  • Cleaning of registers, grilles, and accessible return vents
  • Sanitization options upon request (for commercial or healthcare settings)


We do not over-recommend duct cleaning. If your system is clean and performing well, we’ll let you know — no pressure, no unnecessary services.

Step 3: Sealing & Repairs (If Needed)

If we identify disconnected joints, leaks, or collapsed ductwork during inspection, we’ll provide repair recommendations and transparent pricing. This includes sealing gaps, reconnecting loose lines, and replacing damaged sections as needed.

What’s Hiding in Your Ducts?

Most property owners rarely think about their ductwork — until something goes wrong. Dirty or damaged ducts can contribute to:



  • Excess dust on surfaces and in vents
  • Respiratory irritation, especially for seniors or those with allergies
  • Uneven heating and cooling across zones
  • Increased utility bills
  • Musty or stale odors throughout the building
  • Overworked HVAC systems that wear out faster


If your tenants or employees are complaining about poor air quality or your energy bills are higher than expected, dirty ducts may be the hidden issue.

Who We Serve

We perform duct inspection and cleaning for both commercial and residential clients, with a strong focus on:



  • Restaurants & kitchens – Grease and smoke buildup in supply and return ducts
  • Hotels & multi-unit buildings – Dust, mold, or pest issues from shared ductwork
  • Offices & retail – Duct obstructions reducing comfort and airflow consistency
  • Apartment complexes – Move-out cleaning, turnover readiness, or general maintenance
  • Homeowners & seniors – Improved indoor air quality and system efficiency


No matter the size of your property, clean ducts make a difference — not just for comfort, but for health and performance.

Benefits of Duct Cleaning

Routine duct cleaning isn’t a marketing gimmick — it’s a practical step in system maintenance, especially when done professionally. Some of the key benefits include:



  • Improved Indoor Air Quality - Reduces airborne allergens, mold spores, and particulates, helping sensitive individuals breathe easier.
  • Greater HVAC Efficiency - Clogged ducts reduce airflow, forcing your system to work harder. Cleaning restores full performance and lowers utility usage.
  • Extended System Life - When your furnace or AC isn’t straining against resistance, it lasts longer and requires fewer repairs.
  • Cleaner Living & Working Spaces - Less dust blowing through vents means fewer airborne particles settling on furniture and surfaces.
  • Odor Elimination - Duct cleaning helps remove odors caused by trapped moisture, pets, cooking, or mildew.

Signs Your Ducts Need Attentio

If you’ve noticed any of the following, it may be time to schedule an inspection:



  • Unusual dust buildup around vents
  • Hot and cold spots throughout the property
  • Unexplained spikes in energy bills
  • Allergy or asthma flare-ups indoors
  • Visible debris inside registers or vents
  • Noisy airflow or reduced performance


We don’t recommend cleaning unless your system truly needs it — but if it does, we’ll show you exactly why and how we can fix it.

FTL Financing Available for Duct Repairs or Upgrades

If your inspection reveals serious duct issues — such as large-scale repairs, complete sealing, or replacements — financing is available through FTL Financing to make the process manageable.



Our team can help you apply and find a plan that fits your budget, especially for multi-unit residential or commercial buildings that require more extensive work.
